However, in actual use, anti-slip conveyor belts, especially point-type anti-slip belts, often have problems with reverse material carrying and material leakage at the discharge position. This not only affects the cleanliness and efficiency of the production line, but may also lead to material waste and production line failure. In order to solve this problem, some measures have been taken in the industry.

[0032] Example 1
[0033] like Figure 1 and Figure 2 As shown, an anti-skid conveyor belt leakage control device includes an anti-skid feeding conveyor belt frame 4, an anti-skid feeding conveyor belt frame 4 is provided with an anti-skid feeding conveyor belt 8, and a blowing device 5 is provided below the anti-skid feeding conveyor belt 8 near the outlet end of the anti-skid feeding conveyor belt 8, and the blowing device 5 includes a blowing pipe 2, a solenoid valve 13, a compressed air supply device and a control device. A plurality of blowing holes 15 are provided on the blowing pipe 2, the control device is connected to the solenoid valve 13, the solenoid valve 13 is connected to the compressed air supply device, and the compressed air supply device is connected to the blowing pipe 2.
[0034] The present application has higher management efficiency: traditional methods such as baffles, scrapers or vacuum cleaners have limited effects in preventing leakage and often require regular maintenance and replacement. The present application can more effectively prevent the reverse carrying of materials through precise compressed air blowing, thereby greatly reducing leakage and improving management efficiency. Lower energy consumption: Compared with existing technologies such as using vacuum cleaners or high-power hair dryers, the compressed air blowing system adopted in the present application has lower energy consumption. The precise control of the solenoid valve 13 ensures the rational use of compressed air and avoids unnecessary energy waste.
[0035] Example 2
[0036] like Figure 1 and Figure 2As shown, an anti-skid conveyor belt leakage control device includes an anti-skid feeding conveyor belt frame 4, an anti-skid feeding conveyor belt frame 4 is provided with an anti-skid feeding conveyor belt 8, and a blowing device 5 is provided below the anti-skid feeding conveyor belt 8 near the outlet end of the anti-skid feeding conveyor belt 8, and the blowing device 5 includes a blowing pipe 2, a solenoid valve 13, a compressed air supply device and a control device. A plurality of blowing holes 15 are provided on the blowing pipe 2, the control device is connected to the solenoid valve 13, the solenoid valve 13 is connected to the compressed air supply device, and the compressed air supply device is connected to the blowing pipe 2.
[0037] like Figure 2 As shown, multiple air holes 15 are evenly spaced along the length of the air pipe 2. The distribution of the air holes 15 should ensure a uniform compressed air spray surface below the discharge point of the anti-slip conveyor belt. The air holes 15 are evenly spaced along the length of the air pipe 2, and the distance between the air holes 15 should be appropriately set based on the width of the anti-slip conveyor belt and the properties of the material to ensure that the compressed air is blown comprehensively and evenly onto the conveyor belt surface, thereby effectively preventing material leakage.
[0038] The line connecting the axis of the air blow pipe 2 and the center of the air hole 15 forms an angle of 30°-60° with the non-slip feed conveyor belt 8. The angle between the air hole 15 and the conveyor belt should be adjusted based on the material properties, conveyor belt speed, and material drop patterns. Generally, the air hole 15 should be angled at a certain angle (e.g., between 30° and 60°) to the conveyor belt surface to ensure that the compressed air creates an oblique blowing force, effectively dispersing the material and preventing reverse drag. Furthermore, the angle between the air hole 15 and the conveyor belt can be flexibly controlled by adjusting the installation angle of the air blow pipe 2.
[0039] The air blowing pipe 2 is a circular seamless steel pipe.
[0040] The compressed air supply device can be a complete compressed air generation and supply system, including an air compressor, an air storage tank, a dryer, a filter and other components. These components work together to compress and purify the air in the atmosphere, and then transport it to the air blowing pipe 2 through a pipeline to provide a stable and continuous compressed air supply for the anti-slip conveyor belt leakage control device.
[0041] The control device is an automated control device based on a PLC (Programmable Logic Controller) or microprocessor. By receiving operating signals from the conveyor motor, the control device synchronously controls the opening and closing of the solenoid valve 13, thereby achieving precise injection of compressed air. The operating principles and selection of the control device are well known to those skilled in the art and will not be elaborated upon here. The control device can also be configured with various operating modes to accommodate different operating environments. Furthermore, the control device can include fault detection and alarm functions to ensure safe and reliable operation of the device.
[0042] The control circuit of the anti-slip conveyor belt leakage control device includes a live wire of the power supply line, a neutral wire of the power supply line, an auxiliary contact 12 of the motor contactor, and a solenoid valve 13. The live wire of the power supply line is connected to a first circuit fuse 10, which is connected to the auxiliary contact 12 of the motor contactor, which is connected to the solenoid valve 13. The solenoid valve 13 is connected to a second circuit fuse 11, which is connected to the neutral wire of the power supply line. The first circuit fuse 10 and the second circuit fuse 11 are fuses.
[0043] L: represents the live wire in the power cord, which is usually used to provide power to the circuit.
[0044] N: represents the neutral wire in the power line, which is used for the return flow of current.
[0045] Fuses are used to cut off current when a circuit is overloaded or short-circuited, protecting the circuit from damage.
[0046] When the conveyor belt motor starts, the control system receives the motor's operating signal. Simultaneously, the PLC or microprocessor in the control system sends a control signal to solenoid valve 13 according to pre-programmed logic, causing it to open. At this point, compressed air from the compressed air supply passes through solenoid valve 13 and enters air pipe 2. It is then ejected through air holes 15 in air pipe 2, creating a compressed air blowing force against the surface of the anti-slip conveyor belt.
[0047] When the conveyor motor stops, the control system simultaneously closes solenoid valve 13, halting the compressed air injection. This entire control process is synchronized with the conveyor motor, ensuring the accuracy and efficiency of compressed air injection. The control system also features fault detection and alarm capabilities. If a circuit fault occurs, the control system will issue an alarm signal, alerting the operator to address it promptly.
[0048] The air blowing holes 15 are provided in multiple rows.
[0049] The blowing device 5 is installed on a blowing device frame 14 , and the blowing device frame 14 is fixed on the anti-slip feeding conveyor belt frame 4 .
[0050] A belt guard 1 is attached to the exterior of the blowing device 5 and the anti-slip feed conveyor belt 8. The belt guard 1 prevents material from falling out of range during conveying. The outlet end of the anti-slip feed conveyor belt 8 is wrapped around the passive roller 6. After passing over the passive roller 6, the anti-slip feed conveyor belt 8 passes through the conveyor belt support roller 7 and the conveyor belt reversing pulley 9, moving toward the inlet end. A material receiving conveyor belt 3 is located below the belt guard 1. A driving roller is installed at the inlet end of the anti-slip feed conveyor belt 8. The driving roller is connected to an external power source.
[0051] This application combines compressed air injection technology with solenoid valve 13 control to achieve the goal of preventing material leakage during the operation of the anti-slip conveyor belt. The device mainly consists of an air blowing pipe 2, a solenoid valve 13, a compressed air supply system, and a control system. The air blowing pipe 2 is installed below the discharge point of the anti-slip conveyor belt, with one end of the steel pipe aligned with the conveyor belt. The steel pipe is perforated with holes facing the conveyor belt to allow compressed air to be sprayed into the conveyor belt when needed.
[0052] Compressed air is provided by a dedicated compressed air supply system that ensures a stable and continuous supply. When the anti-slip conveyor belt starts, the control system simultaneously opens the solenoid valve 13 connected to the motor. The opening and closing of solenoid valve 13 is synchronized with the operation of the conveyor belt, ensuring that compressed air is immediately delivered to the conveyor belt when it starts.
[0053] This method of injecting compressed air can effectively prevent the material on the anti-slip conveyor belt from being carried back due to inertia or adhesion, thereby avoiding the occurrence of material leakage. At the same time, since the solenoid valve 13 is controlled synchronously with the motor, the injection of compressed air is more accurate and efficient, which not only saves energy but also improves production efficiency.
[0054] Furthermore, the device boasts a simple structure, easy installation, and low maintenance costs. The durability of the air blow pipe 2 and the rationality of the perforation design ensure the stability and durability of the blowing effect. The precise control of the solenoid valve 13 further enhances the reliability and safety of the entire system.
[0055] To sum up, the anti-skid conveyor belt leakage control device proposed in this application achieves effective control of the anti-skid conveyor belt leakage problem through innovative compressed air blowing technology and solenoid valve 13 control, providing an efficient, clean and low-maintenance solution for the material transportation field.
